Birthday

Sims can choose to throw a party to commemorate their birthday. Birthday parties normally can only be thrown on the day the Sim ages up, although birthday parties can be thrown at any time in The Sims 3. In The Sims 4, Sims who don't blow out their candles, or who fail to throw a birthday party in time, will receive a sad "Forgotten Birthday" moodlet.


 * Using the testingcheatsenabled true, players can age up Sims by shift-clicking one and choose the "Trigger Age Transition." That way, players can make them die from old age instantly as well.
 * Throwing a birthday party and blowing out candles on the cake will give positive moodlets.
